GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate the veracity of this statement by comparing it with a half century of prompt gamma-ray burst observations.

GECAM Localization of High-energy Transients and the Systematic Error
The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a pair of microsatellites (i.e., GECAM-A and GECAM-B) dedicated to monitoring gamma-ray transients including the high-energy electromagnetic counterparts of ...

Gamma-ray Vortex Burst in Nonlinear Thomson Scattering with Refocusing Spiral Plasma Mirror
The gamma-ray vortex burst in the nonlinear Thomson scattering when the laser wakefield accelerated electron bunch collides with an ultra-intense Laguerre–Gaussian laser that was reflected from the refocusing spiral plasma mirror.

GAMMA RAY BURST FOLLOW-UPS WITH BOOTES
The Burst Observer and Optical Transient Exploring System (BOOTES), is a global robotic observatory network, which started in 1998 with Spanish leadership devoted to study optical emissions from gamma ray bursts (GRBs) that occur in the Universe.

Size of shell universe in light of Fermi GBM transient associated with GW150914
The possible burst occurred in location and temporal consistence with gravitational wave event GW150914, as reported by Fermi GBM, offers a new way of constraining models with extra dimensions.

Gamma-Ray Burst Prompt Correlations
The mechanism responsible for the prompt emission of gamma-ray bursts (GRBs) is still a debated issue. The prompt phase-related GRB correlations can allow discriminating among the most plausible theoretical models explaining this emission.

Light speed variation from gamma ray burst GRB 160509A
It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light speed.

Polarized Emission from Gamma-Ray Burst Jets
I review how polarization signals have been discussed in the research field of Gamma-Ray Bursts (GRBs). I mainly discuss two subjects in which polarimetry enables us to study the nature of relativistic jets.

Numerical modelling with analytical estimation of the free parameter space of GRB afterglows: The case of GRB 221009A [PDF]
On date 9th of October 2022, an exceptionally bright Gamma-Ray Burst, GRB 221009A, was detected by several observatories, both ground- and space-based.
